Abstract: 949,844. Inductors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 7, 1961 [July 8, 1960], No. 23963/60. Heading HIT. [Also in Division G1] A cylindrical coil former having a helical conductive path has an adjustable stressing means capable of applying to the former a longitudinal stress either compressive or tensile so as to correct any pitch error evenly distributed along the helical path. In Fig. 1, the grooves 4 for the conductor are deliberately machined so that the actual pitch exceeds the required pitch and the tubular former 1 is compressed to the required extent by tightening nuts 8, 9 on a rod 7. Alternatively, the pitch of the grooves 4 (Fig. 2) may be machined so that the actual pitch is less than the required pitch and the tubular former 1 is internally threaded at each end to engage bolts 12. The former is stretched by turning one or both bolts so as to compress a spacer 11 within the former. Other embodiments (Figs. 3 and 4, not shown) describe a means of tensioning or compressing a tubular former wherein the helical conductor path is on the inner periphery of the former. The conductive path may be conductive wire or strip secured by partially embedding in the machined grooves or may be a printed circuit. The application to position sensing transformers, where accurately dimensioned pitches of the associated windings are important; is suggested. Specification 948,070 is referred to.

Title: Cryosurgical instrument
Inventor: CROFT ANTONY JULIAN
IPC: A61B18/02
Filed: 1969-05-12
Abstract: 1,244,276. Cryosurgical instrument. A. J. CROFT. 3 April, 1970 [12 May, 1969], No. 24138/69. Heading A5R. A cryosurgical instrument comprises a probe 3 cooled by the controlled evaporation of liquid nitrous oxide. The flow of N 2 O from the reservoir 19 into the heat exchanger 25 is regulated by a capillary valve 15 and a needle 5 attached to a piston 6. In operation, a pressure release valve 13 above the piston is opened causing the piston to rise until it is obstructed by stop 7. Liquid N 2 O flows into the heat exchanger where it evaporates cooling the probe to -60‹C in a few seconds. If the pressure release valve is closed, vapour passing from the reservoir through a small hole 11 in the piston equalises the pressure above and below the piston so that a spring 8 is able to close the needle valve. A temperature sensor may be attached to the heat exchanger and the operation of the pressure release valve triggered by a signal received from the sensor. In this way control of the probe temperature may be made automatic. The probe may be provided with an electric heating coil that permits rapid heating after cooling.

Title: Improvements in machines for plugging the mouths of receptacles with soft resilient material
Inventor: SHELLMAN VERNELL ROGER
IPC: B01L3/14
Filed: 1964-06-11
Abstract: 1,013,486. Applying Closures. UPJOHN CO. June 11, 1964, No. 24285/64. Heading B8T. A machine for plugging the mouths of receptacles with soft resilient material, e.g. for inserting cotton wool into the mouths of pipettes, has a recess 132, Fig. 9, in a plate 131 for locating the receptacle mouth, a pair of gears 102, 103, Fig. 6, for feeding a portion of resilient material into alignment with the mouth, a reciprocating pusher with a needle 63 which moves into and out of the mouth and engages the material and inserts it. The pusher driving mechanism is brought into operation in response to the presentation of the receptacle to the plate 131 which is thereby pivoted to operate a switch, whereupon the means for feeding a strand of material into position is operated. As described, a strand of cotton wool is drawn downwardly through a tube 113, Figs. 6 and 9, by the gears 102, 103 and located in front of the needle when the needle pusher or plunger is moved forwardly; the lower end of the strand is then clamped between fixed and movable plates 89 and 121, respectively, Figs. 9 and 12, and a portion of the strand is cut from the remainder by a scissors action between a fixed plate 82 and a pivoted plate 91, Fig. 6; further advance of the needle causes it to engage the central part of the cut-off portion and feed it into the pipette mouth. The needle carrying head 41, Fig. 5, is screwed on to the forward end of the ram of a pressure fluid motor longitudinally supported between side plates 7, 8, Fig. 12, and automatically controlled electrically to reciprocate the head. For this purpose switches are appropriately located on the machine to be operated by the longitudinal movements of the parts. As the head moves towards the pipette a bell-crank 54 thereon contacts one of a ring of pins 117 on a gear 114 which is thus partially rotated and drives, through further gearing, the strand driving gear 102. At the extreme forward position of the ram the bell-crank is turned so that on the return of the ram to its rearward position the bell-crank does not contact the pins 117. The head carries guide rollers 67, 71, and a further roller 69 thereon engages the pivoted shear plate 91 to cause it to cut-off the cotton wool strand; on the return movement of the head the roller engages the rear of the shear plate to return it to its open position. The movable plate 121 of the strand clamping device is secured to a pivoted arm 122 having a cam portion 124 which is engaged by a further roller 68 on the head whereby the strand is clamped in position when the head is in a forward position.

Abstract: 262,548. Howard, Ltd., J. & F., and Jones, L. W. Sept. 30, 1925. Surface-grading machines. - A road-grading machine or like machine having a cutting blade is arranged so that transverse adjustment of the frame 1, Fig. 2, and angular or pivotal adjustment of the rear wheel axle 17, can be effected independently by means of a single operating member 24, located in a definite position on the machine and adapted to be operated for making either of the two adjustments whilst in that position. The operating member is in the form of a rod 24, Fig. 3, having a sleeve 26 slidably keyed thereto at 27. In the lowest position of the sleeve a pinion 28 mounted on the sleeve is arranged to mesh with a gear-wheel 20 secured to a pinion 19 rotatable on a pin 21, and the pinion 19 is in engagement with a rack-bar 18 mounted on the rear wheel axle 17. Rotation of the rod 24 by a hand-wheel 25, when the sleeve is in its lowest position, causes transverse movement of the frame. The sleeve is held in position for operating the frame by means of a catch device 30, a foot lever 29 being employed for bringing the sleeve to such position against the action of a spring 31. When this mechanism is to be put out of action and the sleeve is in its upper position, a locking member 32 is pressed by the spring 31 into a position in which it engages the gear-wheel 20 and also fits a slot 33 in the casing 22, enclosing the gear members. In the upper position of the sleeve 26, a pinion 34 on its upper end meshes with a gear-wheel 35 on a rotatably-mounted rod 36. Chains 38, fixed by clips 40 to the ends of the axle 17, are attached to a pulley 37 on the rod 36. In this position, rotation of the rod 24 causes angular movement of the axle. The axle-adjusting means are locked when the frame 1 is to be moved transversely by means of a foot lever 41, Fig. 5, an extension 42 of which co-operates with a plunger 43. The plunger, which is forced upwardly by a spring 44, is non-rotatable and is provided with gear teeth which mesh with the gear-wheel 35 when the foot lever is out of operation. The lever 41 is held in depressed postion by a catch 45. A cutting blade 4 is carried in such a manner that it can be angularly moved around a vertical axis by a rotatable gear-ring 5 and a bevel pinion 6 operated by a hand-wheel 7, Fig. 2. The blade is also transversely adjusted by a handwheel 8 and rack and pinion gearing 9. Angular adjustment of the blade on a horizontal axis is obtained by link and lever mechanism 10, 11, 12 connected to each side of the gear-ring 5, and the link 12 is in the form of a rack 13 which is operated through gear-wheels 14, 15 and a handwheel 16.

Title: Improvements relating to the treatment of plants to obtain fibres therefrom
IPC: D01B1/10
Filed: 1922-09-11
Abstract: 199,346. Tropical Fibre Corporation, (Assignees of Lowry, G. A.). June 17, 1922, [Convention date]. Breaking and scutching apparatus.-Leaves, stalks, stems, and other portions of fibrous plants, particularly those of the bromelia family, or banana or plantain trees, or musa textilis, are submitted to a crushing and scraping action and then to a shredding or cleaning action. The two apparatus may be used independently or successively, the material being placed in a trough and cut into suitable lengths intermediate of the two apparatus, and the whole treatment being continuous. The crushing and scraping apparatus comprises three crushing rollers 16, 17, 18, Fig. 11, the upper one being mounted in spring-controlled sliding bearings 19, which also have a slight lateral play. A scraper 25 clears the roller 16 and guides the material to the nip of the rollers 17, 18. The scraper is controlled by a spring 28 and is provided with a hole to allow expressed juices to run off. The material passes from the rollers over a pivoted spring-supported concave apron 32 and is acted upon by a rotary scraper 37 with radial blades 30. An extension 36 of the apron 32 acts as a scraper for the roller 17. The material may pass from the rollers between two rotary intermeshing scrapers, the blades of the upper scraper being adjustable radially to vary the action. As an alternative, the lower scraper may be mounted in pivoted arms and pressed towards the upper one by springs. The edges of the blades of the scrapers may be convex in shape to separate laterally the fibres over which the blade moves. The material delivered from one or more of these apparatus is placed in a trough and severed into the desired lengths by a suitable cutter. This material is then placed on the table M, Fig. 2, of the shredding and cleaning apparatus and is passed forward to a device comprising a series of spaced-apart discs 55, round the edges of which are blades 58 with curved penetrating points. A carrier chain 60, Fig. 4, with pins 61 upon which the leaves 62 are impaled moves over one side of the table M and carries the leaves forward in a diagonal direction to the discs 55. The leaves are thus fed forward in the direction of their length and at the same time given a lateral travel. The leaves are maintained in their correct position, whilst being operated upon, by,upper spiked chains 64, 65. These chains pass over sprockets carried by pivoted arms 67 supported by spring rods 68. The slack is taken up by spring-controlled shoes 70. The fibres may be held up against the discs 55 by a rotary fan device 74. The blades on the discs are cleaned by a brush 75. If one portion of the leaf &c. has been shredded and it is desired to treat the remaining portion, the leaf may be wrapped round a rod 80, Fig. 8, and inserted in a clamp comprising a U-shaped portion 78 with hooks 79 at each end of the arms.
